시험관 내(In vitro)
Calpeptin inhibits 20K phosphorylation in a dose-related manner in platelets stimulated by thrombin, ionomycin or collagen. In differentiating PC12 cells, this compound promotes neurite elongation via inhibition of Calpain activity. In rat retinal ganglion cells, it attenuates apoptosis, maintains normal whole-cell membrane potential, and thus provides functional neuroprotection.
생체 내(In vivo)
In a feline right ventricular (RV) PO (RVPO) model, calpeptin (0.6 mg/kg, i.v.) blocks the activation of calpain and caspase-3, cleavage of their substrates, and cardiomyocyte programmed cell death. In a rat focal cerebral ischemia–reperfusion injury model, this compound reduces the neuronal apoptosis in hippocampal CA1 sector via inhibition of the expression of Caspase-3.
